WILLIAM G. \VOLFE, OF HAGERSTOVVN, MARYLAND.

STEAM-PUMP FOR PORTABLE STEAM ENGINES.

SPECIFICATION forming part of Letters Patent No. 298,435, dated May 13, 1884.

Application filed August 20, 1883. (No model.)

To aZZ whom it may concern.-

Be it known that I, XV. O. WOLFE, of Hagerstown, in the county of Vashington and State of Maryland, have invented certain new and useful Improvements in Portable Steam- Engines; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in steam-pumps for portable steam-engines; and it consists in the combination of the engineframe provided with horizontal flanges, which are connected together by a slotted crossflange, the feed-pump, the removable valvechamberswhich are applied to opposite sides thereof, and suitable clamping devices for clamping the pump and valve-chambers in position, as will be more fully described hereinafter. I

Figure 1 is a side elevation of the engineframe,the pump being shown in section. Figs. 2, 3, 4, 5, 6 are detail views of the valves and valve-chambers. Figs. 7 and 8 are vertical sections taken at right angles to Fig. 1.

A represents the engine or pump frame, upon one sideof which areformed thetwo flanges B, which are .united together by the vertical cross-flange G, which is provided with the'slot b. In between these nearly-horizontal flanges is placed the feed-pump D,which may be either of the construction here shown or any other that may be preferred. Upon the inner end of this pump is formed a screw-bolt or stud, a, which passes back through the slot 1) in the flange C, so as to receive a nut or other tightening device, at, for the purpose of assisting to secure the inner end of the feed-pump in position. The outer end of this pump D is made of such a width and thickness as to just fill the space between the two flanges B, and hence does not need any special tightening device at this end to hold it in place. The inner end of the pump is made comparatively narrow for the purpose of allowing the. removable valve-chambers O to be applied to opposite sides, as shown in Fig. 1. In these chambers O are placed the valves R and the removable guides S. The upper ends of the valvechambers O are recessed, so as to allow the guides S to be inserted in the recesses, and thus bring the upper ends of the guides just flush with the top of the chambers. By this construction, when the valve-chamber is removed, the valve and its guide is removed with it. These chambers are loosely applied to opposite sides of the inner end of the pump, and are only separated from the pump by means of washers which are placed between them. \Vhen the inner end of the pump is loosened, these chambers can be readily removed by hand for the purpose of cleaning or repairing the valves.

Applied to the under side of the lower valvechambers, O, is asection pipe or coupling, P,which passes down through the tighteningnut Q upon the opening which is made through the lower flange. This nut Q bears against the under side of the coupling P, and as the coupling 1? bears against the under side of the chambers 0 it is only necessary to screw up the nut Q. when the valve-chambers and the pump will be rigidly clamped together between the coupling Pand the upper flange, B.

\Vh'en it is desired to remove the pump or the valves, it is only necessary to loosen the nut Q and the nut d,when the coupling P will drop down and the inner end of the pump will be released, so that the chambers O can be taken out without the slightest trouble. In tightening the inner end of the pump in place it is necessary to tighten the nut d, as well as the nut Q, and when it is necessary to remove both the valve-chambers it is necessary to loosen both nuts, so that the rear end of the pump can be moved sufficiently for that purpose. The water from the pumpis forced by the piston 9 through the passage T into the air-chamberU,and from this chamber the water passes down through the passage V,which is cast in the frame A, and through the pipe W into the heater. -For the purpose'of allowing the water to pass through the chamber U, there are two openings made through the upper flange, as showniu Figs. 7 and 8.

Having thus described my invention, I

cl itlIll-r 1. lhe combination of the frame provided with suitable flanges, the feed-pump, thedetachable valve-chambers applied thereto, and the clamping device for clamping the pump and the chambers against the upper flange of the frame, substantially as shown.

2. The combination of the frame A, provided with the flanges B and slotted flange G, the pump, the removable va1ve-chambers,the air-chamber U, and a suitable pipe, V, for connection with the air-chamber, the pump and the valve-chambers being clamped together against one of theflanges on the frame, substantially as described.

3. The combination of the pump, the frame A, provided with the flanges B, the valvechambers O, recessed at their upper ends,the

removable guides, which are inserted in the chambers so as to be flush with their tops, and
